An unknown material has a mass of 6.25 g and a volume of 7.75 cm3. what is the density of the material? round to the nearest tenth.

density equals:  806451.61290323

The density is 0.8064516129.

Explanation:

To find the density of any object, you need to know the Mass (grams) of the object, and its Volume (measured in mL or cm³). Divide the mass by the volume in order to get an object's Density. And das what I did.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
